Why aren't the Android SDK Jars in any Maven Repository?

Question

Is there any reason that the Android toolchain and development jars aren't in the Maven CEntral repository? Is it really just that no one has done it? or are there some licensing issues? I mean it's all open source right? (except for the Google APIs).

I'm tempted to put it up myself in a non central repo, but I just want to be sure that someone else hasn't done it yet and that I won't be corresponding or playing telephone tag with any lawyers as a result.

Answer 1

Google blocked it. From this link:

The Android artifacts have been built and published to the Maven repository through the efforts of the Android for Maven project. Google prevented the official Android jars from being uploaded to Maven, so the, third party, Android for Maven project was started to provide an API compatible Android artifact that could be uploaded to the Maven repository. There are now artifacts for each major Android version available in the Maven repository. These are not functional, however, and only provide stubbed implementations of the API. All methods in all classes throw a runtime exception. Because an Android app runs on a device, it will never use these libraries for execution, but the API compatibility allows an app to be compiled as if it were the real library.

Answer 2

Google now has an official maven repository announced at Google IO 2017.

buildscript {     repositories {         maven {           // Google Maven Repository           url 'https://maven.google.com'         }     }     ... }
